You would think betfair would easily cover the 3% considering its usually the longer shots where you get the good odds.

By moving up to the true roughie zone but kicking out the despised longer roughies results may improve.

1. Don Scott Rank 1 - 5
2. Runners 14 and greater
3. 100 Unitab rater
4. Price $16.00 - $26.00 (15/1 to 25/1)



Very small sample but perhaps worthy of further investigation.

Selections: 72
Wins: 9
Return: $172
SR: 12.5%
POT: 139%

Also another filter to use is career starts.

Basically the base rating for the Don Scott Worksheet is the best of the last 3 runs.

So a horse can have 2 starts and be at 60. then it can jump to 24.
